Inheritance

While inheritance can make management easier, it also can result in unnecessary duplication.

Permission analysis analyzes inheritance by determining whether a business resource inherits permission, and whether a specific permission is inherited.

The table below lists the relationships involved in permission analysis.

Business Resource Inherits Permission	Permission is Inherited	Result
True	True	The permission is not unique and derives from the father permission.
True	False	The permission is unique and even though the business resource inherits permissions, the specific permission is not inherited. This is a common scenario in NTFS.
False	False	The permission is unique.
False	True	The permission is unique.

Note: The last case in the table is a situation that occurs in a few specific end systems (as it is logically inconceivable). For example, the system enforces SharePoint Policy Rule Permissions from the Web application level. Therefore, even if the business resource does not explicitly inherit any permissions, permissions are still inherited.
